Hallo Matthias Apsel,

falls es jemand ausprobieren möchte:

#content {
  max-width: 35em;
}
.note-box-example {
  border-left: 5px solid #dfac20;
  padding-left: 15px;
  overflow: visible;
}
.note-box-example > div {
  padding: .5em 0 !important;
  border: none !important;
  background: none !important;
}
.note-box-example > div:last-child {
  padding-bottom: 0 !important;
}
.note-box-example .note-box-title {
  color: #333;
  background: none;
  border: none;
  font-weight: bold;
  font-size: 100%;
  padding-top: 0  !important;
}
.note-box-example .note-box-title .beispiel_url {
  color: #2673bf;
  white-space: nowrap;
  margin: 0;
}
.note-box-example .note-box-title .beispiel_url_code {
  color: #2673bf;
  white-space: nowrap;
  margin: 0;
}
.note-box-example .note-box-footer {
  display: none;
}
.note-box-example-code {
  width: 65em;
}

Bis demnächst
Matthias
